.To aZZ whom it may concern.-

Be. it known that I, EBEN (J. WILLEY, a citizen of the United States,residing at Manchester, in the county of Hillsborough and State of NewHampshire, have invented a certain new and useful Improvement in Saddlesfor Drawing-Rolls of Spinning and Twisting Machines, of which thefollowing is a specitication.

My invention relates to saddles for drawingrolls of spinning andtwisting machines; and it consists in the devices and combinationshereinafter described and claimed, the object of which is to facilitatethe lubrication of the bearings of said saddles.

In the accompanying drawings, Figure 1 is an isometric view of a set ofdrawing-rolls and saddles as used in a spinning-mule, the arbors of saidrolls being in section Fig. 2, a section of the top rolls shown in Fig.1, and of the lower saddle, and a side elevation ofthe upper saddle,said section being a longitudinal ver tical section through the middleof the lower saddle. Figs. 3 and 4 are respectively plans of the top andbottom of the lower saddle shown in Figs. 1 and 2; Fig. 5, a verticallongitudinal central section of the saddles of the drawing-rolls of aspinningframe and a transverse section of the top rolls between thebosses of the same; Fig. 6, a plan of the middle portion of the toprolls and saddles shown in Fig. 5; Fig. 7, a central longitudinalsectional elevation of a saddle and drawing-rolls as used in afly-fraine; Fig. 8, a plan of the bottom of the saddle shown in Fig. 7.

The lower drawing-rolls, D D D are commonly steel rolls flutedlongitudinally and having necks or reduced portions (1 d (P, which turnin bearing-notches in suitable rollerstands, (not shown,) as is wellknown, and the top rolls, T T T, are commonly covered with leather andrest upon the lower rolls, there being two bosses or top rolls on asingle arbor, t 15 t slightly separated fronieach other, the arborsbetween said bosses or top rolls serving as thejournals of the toprolls. On the-lastnamed journals rest suitable saddles. In a mule thereare three pairs of rolls, as shown in Figs. 1 and 2. On thejournals ofthe middle and back roll rests the lower saddle, S,

which is substantially of the shape commonly used, except that it isprovided at each end with a groove, 8 s, whichextends from the top ofthe saddle over the end of the same and on the under side of the same toits bearing on the journal or arbor t i The grooves s s are inclineddownward all the way from their upper ends to the bearing-surfaces ofthe lower saddle, so that a drop of oil poured into either of saidgrooves on the top of the saddle will be conducted to the journal onwhich the saddle contain continuations of the grooves s s, and

prevent oil poured into the top of said grooves from spreading out overthe lower edge of said upper saddle; and except, also, a thirdoilgroove, 8, whiclrreaches from the inclined upper surface of the frontend of said saddle S down to the bearing-surface of the arbor 1/ of thefront top roll, T, said last named oilgroove constantly descending fromits highest part to said bearingsurface.

All of the oil-grooves above named are formed partly in the ends oftheir saddles; except the grooves 8" s, which run nearly vertically onthe side of the upper saddle and discharge into the oil-grooves of thelower saddle, and all of said grooves are enlarged at their upper ends,

tofacilitate the reception of oil. The oilgrooves formed partly in theends of the saddle preferably terminate at their lower ends in atransverse groove, r, as shown in Figs. 2 and 4, adapted to contain anaccumulation of oil at the bearing-surfaces.

The upper saddle, S, is provided near its front end with a vertical pin,0, which serves to retain on the saddle a roll (not shown) used to catchlint, and is also provided with a book, 1), a part only of which isshown,which serves to support a weight (not shown) in the usual manner,to increase the pressure of the top rolls upon the fluted rolls.

The saddles shown in Figs. 5 and 6 are of the common form used inring-spinning frames and differ from those in common use only in havingoil-conducting grooves, substantially like those above described asbelonging to the saddle S.

In Figs. 5 and 6 the lower saddle, U, rests upon the journals of themiddle and rear top rolls, T T, (these top rolls being substantiallylike those shown in Figs. 1 and 2,) and the upper saddle, V, rests atits front end upon the front top roll, T, while its rear end rests uponthe lower saddle, U, pressure being applied to the top rolls by a weightsuspended from a sheet-metal hook or link, f, a part only of which isshown. The lower saddle, U, is pro vided at each end with oil-grooves ua", which are enlarged at the top and run down over the ends of thesaddles to the bearing-surfaces, and terminate in transverse grooves a"m, which serve the same purpose as the grooves r, shown in Figs. 2 and4, and above described. The upper saddle, V, is also provided withoil-grooves, which lead from its upper surface at v v to itsbearing-surfaces, the groove '0 terminating in a transverse groove, 11",at the journal of the front top roll, and the groove '0' discharginginto the groove to, which con ducts the oil to thejournal of the middletop roll, T".

In Figs. 7 and S a saddle is shown of the form commonly used infiy-frames. This saddle, V,is provided with oil-grooves w it", whichlead from its upper surface over its ends to the journals of thedrawing-rolls T T and terminating in transverse grooves 10' wflwhichhold an accumulation of oil on said journals. The last-namcd oil-groovesconstantly descend from their highest parts to said last-namedtransverse grooves.

The oil-grooves above described are less lia-- ble to become cloggedthan oil-holes, and are very easily cleaned and conduct the oil withfacility and certainty to the journals of the drawing-rolls.

I am aware that saddles have been made with recesses or chambers intheir upper surfaces to contain wads of felt or other suitable materialsaturated with oil or other lubricating compound, which passes throughsmall holes leading from the bottoms of said recesses and dischargingupon. ungrooved surfaces or ends of such saddles, the oil or lubricatingcompound not, however,being directed by grooves or channels from thelower ends of said holes to the bearing-surfaces of said saddles. Such aconstruction I do not claim.

I am not aware that an open groove situated partly in the top of asaddle and leading from the top of the same to the bearing-surface ofthe same has ever been used.

I claim as my invention 1. A saddle for drawing-rolls, provided with oneor more open grooves extending from the upper surface thereof to thebearing-surface ofsaid saddle, as and for thepurpose specified.

2. A saddle for drawing-rolls,provided with Oil-grooves extending fromthe upper surface thereof and over the ends thereof to the hearingsurfaces of said saddle, as and for the purpose specified.

3. A saddle fordrawing-rolls,provided with oil-grooves arranged in thetop ends and bottom of said saddle and constantly descending from thehighest parts of said grooves to the bearing-surfaces of said saddle, asand for the purpose specified.

4. A saddle for drawing-rolls, having an oilpassage leading from theupper surface thereof to the bearing-surface of said saddle andterminating at said bearing-surface in a transverse groove or lateralenlargement to receive and retain oil, as and for the purpose specified.

5. A saddle for drawing-rolls,provided with oil-grooves extending fromthe top of said saddle to the bearing-surfaces of said saddle andterminating at said bearing-surfaces in transverse grooves or lateralenlargements at said bearing-surfaces, as and for the purpose specified.

6. The combination of a saddle provided with oil-grooves arranged in thetop ends and under surface of said saddle and terminating at thebearing-surfaces of said saddle, in combination with another saddleadapted to be supported partly by said first-named saddle and providedwith one or more oil-grooves extending from the top to the bottomthereof and adapted to discharge oil placed in said last-named groovesinto one or more ofsaid oilgrooves in said first-named saddle, as andfor the purpose specified.
